What Is A Thermoelectric Wine Cooler?

A thermoelectric wine cooler operates on a principle known as the Peltier effect. Basically, when two metal plates are placed together and electricity is passed through them, something interesting happens -- one plate gets cooled while the other gets hotter!

Because of this, this type of cooler makes almost no noise and doesn't vibrate at all and most thermoelectric coolers can't get lower than 50°F. With only a few being able to get as low as 45°F.

Here's a short and simple explanation of how the Peltier effect creates thermoelectric cooling:


What Are The Advantages Of Thermoelectric Wine Coolers?

The biggest advantage would have to be that they don't vibrate. This means they generally operate silently, compared to compressor wine coolers which are much louder. 

Another important thing to note is because they don't vibrate, the sediment in wine bottles can settle, so your wine won't develop a bad taste.

Here are some more advantages of a thermoelectric wine cooler:

  • They are safe for the environment since they don't need re​frig​er​ants that introduce some hazardous chemicals like CFCs and HCFC-s into the environment. 
  • They have a consistent interior temperature, which will help to maintain, and improve the quality of your wine.
  • They are energy-efficient so you don't have to worry about them increasing your electricity bills.

What Are The Disadvantages Of Thermoelectric Wine Coolers?

The biggest disadvantage of a thermoelectric wine cooler would be that it doesn't get as cold as a compressor wine cooler. Most thermoelectric wine coolers will usually not go anywhere below 50°F.

They also only maintain internal temperature when they're closed. So if they're opened too frequently, the internal temperature would rise and drop frequently which could be bad for your wines.

Because they operate by removing heat rather than producing cold air, they won't work when it's too hot (when the outside template is about 80°F). The cooler would have trouble removing enough heat to maintain the ideal 50°F - 55°F temperature for wine storage.

They also won't work when it's too cold. Since they don't have any way of adding heat, if the outside temperature drops below 50°F, the temperature inside the cooler will also drop. This can affect the conditions of your wine.

Things To Note When Using A Thermoelectric Wine Cooler

Here are some things you should note when using this kind of wine cooler:

  • Make sure to keep it in a space where the ambient temperature is between 50°F and 80°F
  • For freestanding units, you'll need to leave at least 5 inches of allowance around the cooler to allow for proper ventilation. The heat pump of the cooler can overheat and burn out if there isn't enough ventilation for heat dispersal. This is why you should not freestanding units into your cabinetry.

Considerations To Make When Buying A Thermoelectric Wine Cooler

The answer to this depends mostly on your needs.

If you have a large collection that you wish to store for a while, you'll want to go for something with a large capacity.

If you have a small space, you'll want to get something that is compact.

If you plan to install it somewhere tight, like between cabinets (if it's not a freestanding unit), then you'll want to go for something slim.

Another thing to consider is the variety of your wine collection. If you have a mix of red and white wine, there are three different ways you could go about storing them:

  • You can keep the white and red wine together 
  • You can store them separately 
  • You can consider a dual-zone option

If you decide to keep the white and red wine together, and you have no problem waiting for the reds to warm up a little before you drink (it won't take long since thermoelectric coolers don't get very low in temperature) then you can go for any wine cooler that catches your fancy.

What you'd need to consider then, would be the capacity you need, and the amount of space you have to place the cooler in (remember you can't keep them in tight spaces or they overheat and get ruined).

If you want to store them separately, then it might be a good idea to get two small, compact wine coolers. That way you can keep your red and white wines at the right temperature that you like, and your coolers won't take up too much space. 

You can also try a third option, which is a dual-zone cooler. This will allow you to keep your white and red wines in the same place. It'll be cheaper than buying two units, and it'll also take less space.

Basically, how much wine you have to store, how varied they are in type, and in which location in your home or office you'll place them are the 3 most important things to consider when buying a thermoelectric wine cooler. 

Conclusion

The clear winner for us is the Koolatron KWT10BN. But for those who are on a budget, we recommend the Koolatron WC06.

The Koolatron KWT10BN is great because compared to the rest, it's actually quiet. Its unique design makes for an excellent showpiece. It's roomy enough to take up to 10 bottles, with the bottom rack being able to carry bottles like a Burgundy. 

Unlike the rest, where you'd have to start taking out the racks to fit bottles like that. It cools quickly too. So all in all, it's got everything you need in a wine cooler.
